Where should i weld my o2 bung for my AEM wideband?

[MC23]

I was curious if there is a certain place to weld my o2 bung on my downpipe? Also what size hole should i drill?

Thanks

Are you using a cat? If not, just put it in the second o2 bung.


"1. Weld o2 bunge on exhuast at least 36" away from turbo/exhuast manifold.

2. Drill 1-1/8" hole though firewall for the male end of the wiring harness to fit thou. I was not happy about doing this but I could find no other way. I ended up drilling just to the right of the brake pedal bracket with a 1-1/8" bi-metal hole saw."
